To all whom it may concern: turned with respect to each other, as in Be it known that I, FREDERICK Inno rounclin a curve. CASS, a citizen of the United States, residing In or or to allow the tank truck to vary at Clintonville, in the county of Waupaca its lateral vertical angle with respect to the 60 and State of Wisconsin, have invented cerboiler truck, the post 14 has a hol ow tube 18 tain new and useful Im rovements in Tracprojecting forwardly therefrom and extendtion-Engines, of whic the following is a ing through an axial tube. or cylinder 17 specification. within the tank The tube 17 bears upon This invention relates to traction engines, the tube 18, and so they can turn ,wlth re- 10 and has for its particular object to provide spect to each. other, to allow the lateral 1nimproved means for supporting and driving 0 ination of the respective axles to be varied, such an engine. as is necessary in passing over rough roads. Afurther object of the invention is to pro- A steam engine 19 is mounted upon the vide improved means for steering the same. steam boiler and is connected bv The ordinary traction engine has most of the other suitable gearing to the wheels 8, and a weight on the rear wheels, and drives by said steam engine 20 is likewise mounted u on wheels alone. The present engine has a the Water tank 10, and is belted orgeare to driving gear or motor for each set of wheels, the wheels upon which said tank is supportandis so constructed that the water tank is ed. This gives a power. drive at both trucks 5 20 supported upon the front wheels and the or sets of wheels. The engine on the steam boiler upon the rear wheels, and with a moboiler has the usual steam connections with tor or engine, as stated, for each set of the boiler. The engine on the front tank fwheels. Novel connections are provided he has a sup ly connection from the steam tween the boiler and the engine on the tank. dome 21 w iich is mountedon said stank for 25 Also novel steering mechanism for turning the purpose of su plying said engine with the front or tank carriage or truck, for the dry steam. Said ome receives steam from pu iplose of steering thevehicle. the steam boiler 9 through connections ine invention is illustrated in the accomeluding a pipe 22 which extends forwardly panying drawings, in which from the steam dome and downwardly in Figure 1 is a side elevation of the vehicle. front of the tank, a pipe 23, which extends Fig. 2 is' a vertical longitudinal section. axially through the tube 18, a pipe 24 which Fig. 3 is a top plan view. is connected by a universal joint 25 to the Referring specifically to the drawings, 6 pipe 23, and a pipe 26 connected to the indicates a platform or wide sill, which is steam dome 27 on the boiler.- The connec- 90. 35 mountedupon the arched axle 7 supported tions shown are provided in order that meby wheels 8.

Steering is effected by turning the post 14, The water tank 10 is supported upon the which allows the angle of the front and rear front truck consisting of the sill 1.1, axle 12, trucks to be varied. To this end the post has and wheels 13, and is balanced as nearly as a cross bar 28 at the top, the ends of which possible thereon. are connected by links 29 to sleeves 30 on log Aflexible or universal connection between screws 31 which are provided with hand the tank truck and the boiler truck is formed.

The sleeves 30 are" the upper en 'it findsa bearing in a cross mounted in guides 33 on the beam 16, and piece 15 supported by the ends of a pair of the screws 31 are eared together by spureams 16 extending lengthwise along the top wheels 34 so that, t e screws turn in unison of the boiler and securely fastened thereto. but in opposite directions and so pull or push 1 This post provides a vertical axis, which per- 0 positely when the device is belng steered. mits the tank truck and boiler truck to be e screws are held against lengthwise moveelts or 7 the post is turned the angle of the rear truck with respect to the front truck is varied, as

above described.

By the construction shown, the weight of the necessary parts of a steam traction engine are placed upon four wheels, all of which post is turned, means to turn the are used for driving pu oses, with a driving engine for each air. e exhaust from the front engine is t ough a stack 36 and from the rear engine is through the usual smoke stack 37.

I claim: 1. In a traction engine, the combination of front and rear trucks, flexibly connected together, a water tank upon one truck and a steam boiler upon the other, a driving engine mounted upon each truck to drive the same, and having connections to the boiler, and means to steer the trucks.

2. In a traction engine, the combination of two-wheeled front and rear trucks, a turning steering ost at the front end of the rear truck an having a connection to the front truck arranged to turn the same when the ost, and means carried by the trucks to rive the same.

, 3. In a traction engine, the combination of a two-wheeled front truck, a cylindrical water tank mounted thereon and having a central horizontal bearing tube, farear truck, a

steam boiler mounted thereon, a turning steering ost mounted on the front end of the rear true and havin ari id ro'ectin tubeg g J g extending forwardly into sai bearing tube, whereby the tank may turn in a vertical plane with respect to the boiler, and said front truck swing in a horizontal lane to change. the direction of travel, an

mounted on and connected to the trucks to 3 gine mounted upon and having drlving connections to the front truck, and a pi e extendin from the boiler through sai post and tu es and to the engine and having a flexible coupling, and means to turn the post to steer the trucks.

5. In a traction engine, the combination of a front truck, a rear truck, a turning ,post on the rear truck and connected to the front truck to'turn the same, said post'having a projecting arm, a threaded tube connected to said arm, and a steering screw extending into said tube, to move the same.
